In Thailand, this species is considered a rare plant, endemic to only a few places, such as Phu Wiang National Park, Khao Kradong Forest Park, etc. It is known as yoni pisaj (Thai: โยนีปีศาจ, "devil's vagina") or hee phi (หีผี, "ghost's pussy"), because the ripe fruit looks like female genitalia. There is a local legend that says that, Maiden Orapim, followed the man she loved, Prince Panjit, the son of Khmer King. The two were separated by a large, fast-flowing river. Orapim was afraid that crossing the river would be inconvenient because she was a woman, so she prayed to place her breasts on the wild cotton tree (Bombax ceiba) and her genital on weaver's beam tree, and so she transformed into a man and continued to search for Prince Panjit.^[5][6]
